Dominick from Princeton Air arrived on time and immediately identified himself. He was polite and courteous from the get go. He had to troubleshoot my ac unit which stopped working in the middle of a heat wave ( Murphy’s Law). He gave me the bad news that it would be very costly to repair unit as unit is 22 years old and there are numerous problems. I decided to go with a replacement unit, stay tuned…
Kirk Windish

Dominic was fantastic. My air conditioning stopped working I called the Company at 9:30 and Dominic was here at 3:00 he quickly diagnosed the problem, had everything working again in no time, and checked the entire system to make sure everything was running properly.
Professional, knowledgeable, and a pleasure to deal with. I truly appreciated his prompt response and excellent service. Highly recommend!

Ann Marie Barone
Dominic came to my home to evaluate a sudden issue with my HVac unit.
He was smart, polite and helpful. He came in & went right to work.

I highly recommend Dominic as a service technician as he remedied my problem with confidence & skill.

Thank you Princeton Air

JULIA MENDENHALL
I highly recommend Ryan Gobel, technician, of Princeton Air. He did a diagnosis of my boiler's problem and explained calmly the problem. I brought Princeton Air in for a second opinion after a "senior tech" at AJ Perri fast talked me and told me some lie about what was wrong. I canceled them. Got Princeton Air. Ryan came out and said something different and fixed the boiler correctly. He is professional, extremely knowledgeable, and nice. Thank you Ryan and I look forward to seeing you again for the fall maintenance.
Eileen S Robinson
I needed a new HVAC system. From the beginning of the process through the finished installation the McAllister Service Co team was very professional and answered all my questions to my satisfaction. The installation went smoothly and the team did a thorough clean up of the equipment installation locations. I want to say a special thanks to Zeus and Michael D my maintenance reps, Jason L my system and installation project manager, and Joe D, my installation team manager and his team on 6/8.
Fred Mangino
Princeton Air Conditioning replaced my 25 year old central air conditioner. The sales person was very knowledgeable, made sure I was getting the correct size unit, explained the available options and got a quote out very quickly. They were very competitive on price and did an excellent job installing the unit. I am planning on having them provide all maintenance on the unit. I highly recommend Princeton Air Conditioning.
